    • 摘要: 针对椭圆曲线密码系统的标量乘运算开销较大和易受能量分析攻击的问题,提出基于伪四维投射坐标的快速群运算和基于伪四维投射坐标的多基链标量乘法,对椭圆曲线密码系统的群运算层和标量乘运算层进行优化,旨在提高椭圆曲线密码系统的整体性能并抵御常见的能量分析攻击.实验表明,与现有算法相比,所提算法离散群运算的倍点运算开销降低5.71%,三倍点运算开销降低3.17%,五倍点运算开销降低8.74%.此外,在密钥长度为160位的情况下,所提算法连续群运算的三倍点运算开销降低36.32%,五倍点运算开销降低17.42%,系统整体开销降低8.70%.能量波形分析表明,所提算法可以有效抵御SPA攻击和DPA攻击.%In order to address the problem of elliptic curve cryptosystem (ECC) for the expensive cost in scalar multipli-cation and the vulnerability to the power analysis attacks, a pseudo 4D projective coordinate-based multi-base scalar mul-tiplication was proposed to optimize group operation layer and scalar multiplication operation layer, which aimed at in-creasing the performance of ECC and resisting common power analysis attacks. Experimental results show that compared with the state-of-the-art algorithms, the proposed algorithm decreases 5.71% of point doubling cost, 3.17% of point tri-pling cost, and 8.74% of point quintupling cost under discrete group operations. When the key length is 160 bit, the pro-posed algorithm decreases 36.32% of point tripling cost, 17.42% of point quintupling cost, and 8.70% of the system cost under continuous group operations. The analyzing of power consumption wave shows that the proposed algorithm can re-sist SPA and DPA attack.

    • 摘要: 无线射频识别( RFID)是一种可实现自动识别和数据获取的无线技术,其在健康护理领域应用广泛并已成为该领域的主导识别技术。 RFID系统的安全与隐私问题受到越来越多的关注,许多基于椭圆曲线密码系统或Hash函数的认证协议都实现了保护系统安全性和隐私性的设计目标,但很少有协议考虑标签或阅读器破坏条件下的前向安全性。对新近提出的三个安全协议进行了分析,结果表明,三个协议并不能在标签或阅读器破坏下提供前向隐私保护,进而提出一种改进的基于ECC的RFID认证协议,对改进协议的安全性进行了详细分析。结果表明,新协议在满足各安全需求的同时,可以提供阅读器破坏条件下的前向安全性,而且新协议需要的计算开销更少,效率更优。%Radio Frequency Identification ( RFID) is a wireless technology for automatic identification and data capture and is deployed as a dominant identification technology in a health care domain. Security and privacy issues in the RFID systems have attracted much atten-tion,and many authentication protocols based on Elliptic Curve Cryptosystem ( ECC) or Hash functions have been proposed to achieve the security and privacy goals,but seldom protocols have considered the forward security with tag or reader corruption,which can be viewed as the highest level of user privacy. Three recently protocols presented respectively suffer from the forward privacy problem with tag or reader corruption. To enhance the security,an improved efficient ECC-based RFID authentication protocol is put forward. A com-prehensive analysis shows the new scheme can not only provide the strong forward security with reader corruption besides all the other se-curity requirements,but also have more functionality in terms of computational cost.

    • 摘要: 针对故障攻击椭圆曲线点乘算法失效问题,提出一种改进的差分故障攻击算法.该算法消除了非零块的假设,并引入验证机制抵抗了“故障检测”失效威胁.以SM2算法提供的椭圆曲线为例,通过软件仿真成功攻击了二进制点乘算法、二进制非相邻型(NAF)点乘算法和蒙哥马利点乘算法,3小时内恢复出了256比特私钥.针对二进制NAF点乘算法攻击过程进行了优化,将攻击时间缩短至原来的五分之一.实验结果表明,所提算法能够提高攻击的有效性.

    • 摘要: SIP is a widely used signaling protocol in VOIP, which has also been adopted by 3GPP as the signaling protocol for multimedia applications in 3G mobile networks. But the original authentication mechanism in SIP cannot provide security at an acceptable level. Although various schemes have been proposed, they’re still defenseless to all kinds of attacks. This paper makes some changes to the Yoon’s scheme to solve the problem which provides higher security while keeping high efifciency.%SIP是目前VOIP中广泛应用的信令协议,并且已被3GPP作为3G移动网络中的多媒体应用协议。SIP最初的认证机制并没有提供足够高的安全性,不少研究者对此提出了不同方案,但依然面临各种各样的攻击威胁,文章针对Yoon协议加以改进以解决上述问题,改进协议在保持高效性的同时具备了更高的安全性。

    • 摘要: Having high safety and effective computational property,the elliptic curve cryptosystem (ECC) is very suitable for embedded mobile environment with resource constraints.Side-channel attack (SCA) is a powerful cipher attack method,it uses leaking information of cipher-chip in its operation process to attack chip cryptographic algorithms.In view of the situation that the SCA on ECC mainly concentrates on scalar multiplication operation,an improved algorithm FWNAF (Fractional Width-w NAF) based on RWNAF (Refined Width-w NAF) is proposed.This algorithm utilise the fragments window technology,further improves the utilisation ratio of the storage resource and reduces the "jitter phenomenon " in system computing performance caused by the sharp change in system resources.%椭圆曲线密码系统具有较高的安全性和有效的计算性,非常适合于资源受限的嵌入式移动环境.侧信道攻击是一种强有力的密码攻击方法,利用密码芯片在运算过程中泄露的信息对芯片的密码算法进行攻击.针对侧信道攻击椭圆曲线密码系统主要集中在对标量乘运算的攻击,提出一种基于RWNAF(Refined Width-w NAF)的改进算法FWNAF (Fractional Width-w NAF)算法.该算法利用碎片窗口技术,进一步提高存储资源的利用效率,同时也减少由于系统资源急剧变化而引发的系统计算性能的“抖动现象”.

    • 摘要: 身份认证技术是保证无线传感器网络(WSNs)安全的重要技术之一.基于椭圆曲线密码系统(ECC)提出了一种用于分簇WSNs的节点身份认证机制,该机制采用分级的思想将基于非对称密码的复杂运算置于簇头和网络管理者等计算能力强的节点上执行,而计算能力差的普通传感器节点仅承担基于对称密码的简单运算,有效克服了传统的基于非对称密码认证方案计算量大、基于对称密码认证方案安全性差的缺陷.分析表明:与传统的认证策略相比,该方案同时在安全性和效率上具有明显优势.%Identity authentication is critical to the security of wireless sensor networks ( WSNs) . An identity authentication scheme for clustered WSNs based on elliptic curve cryptosystem ( ECC) is proposed. The scheme presents a stratified strategy that the nodes with strong computing ability are responsible for the public key based complex calculations, and the nodes with weak computing ability are responsible for the symmetric key based simple calculations. The analysis shows that, compared with traditional authentication schemes, the proposed scheme has superiority in both security and efficiency.
